基于遗传算法的基站天线赋形波束综合

提出了一种改进的适应度函数确定方法,通过改变适应度函数中的待定参数,有效提高了搜索效率。采用遗传算法对基站天线的方向图赋形,其结果优于同种条件下用WoodWard法得到的结果。结合工程实践,考察了本文遗传算法的解的稳定性。文中的结果对工程和理论研究都具有重要意义。

Pattern Synthesis of Shaped beam for Base Station Antenna Using Genetic Algorithms

One improved method of defining fitness function is presented. Higher efficiency of searching could be achieved by setting undetermined parameter of fitness function. One shaped-beam array antenna is designed using genetic algorithms, the result is better than Woodward. The stability of the answer to GAs is checked for engineering practice. The results of this paper are important either for project or theory.
